An agent can also autonomously perform tasks related with the management of learning resources or the achievement of internal educational goals. This paper presents the definition and classification of educational agents together with their tasks and roles in the educational process. In distance learning environment, agents can improve the motivation and concentration of the students and, consequently, they can improve the effectiveness of the educational process. Agent characteristics and architecture required to achieve educational goals are also described. The paper presents also a prototypical implementation of an educational agent (called the WAS agent) that is developed as a part of our research.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129508327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scans contain the noisy head-cross data and also the noisy background data. The latter have to be removed and excluded from a further analysis.

The results of removing the background from the sequence of scans with the use of some different shapes and sizes of structuring elements are presented in the paper. The aim of this paper is to choose the best structuring elements to make the new method the most immune to various qualities and appearances of the processed MRI images.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122453402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Automatic speaker segmentation alone does not allow for the separation of individual patient case discussions (PCDs). A novel method is presented here, based on Hidden Markov Models (HMM), to segment audio recordings of MDTMs and facilitate the non-linear retrieval of individual PCDs. The method combines professional role interaction with speaker vocalization patterns. The sequence and duration of vocalization and speakerspsila roles are used as training states. Results demonstrate HMM segmentation to have good potential in the development of an MDTM browser. The approach outlined here can be applied in a wide range of meetings.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115062895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach, called Beh-VR, enables dynamic generation of virtual scenes from arbitrarily selected sets of specifically designed reusable virtual objects, called VR-Beans. Presentation and behavior of the objects in virtual scenes is determined by associated scripts encoded in a high-level language called VR-BML. VR-Beans are compatible with existing scene description standards such as VRML/X3D, but are designed according to specific rules enabling the use of these objects in dynamically generated scenes. Further, to simplify the design of complex interactive VR scenes, VR content patterns are used.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115154082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This machine vision system is using small and cheap camera and FPGA postprocessor with wireless network interface. Power for the system will be delivered from solar panels and therefore the system is optimized to be power efficient. In this paper the machine vision traffic jam detection module based on wavelet transform is described. This module correctly detects and measures traffic jams or very slow traffic conditions when background subtraction algorithms (used for vehicle counting) are not suitable. Optical flow algorithms can also be used but they are computationally expensive. Sample discrete wavelet transform based algorithm and its hardware implementation in FPGA are examined in the paper. Hardware accelerated discrete wavelet transform can be also applied to image compression when image has to be transferred to the traffic control center (picture quality and frame rate depends on wireless network quality). Results of sample traffic classification are presented and compared. This work has been supported by the Polish Ministry of Science and Higher Education under R&D grant no.
